You need to take a look at the times that the data for these sources
occur and what the contents of the CL table for those times are, just
as the error message suggests.  It seems unlikely that the
calibrations should fail for all antennas at once, but that can
happen.  There is also possibilities of differing FQ or SUBARRAY for
these times.  SNPLT is one way to look at the CL table although PRTAB
may in the end be necessary.
